Samsung produce a range of players, many of which support Vorbis to a greater or lesser degree.
The YP-T6 is an incredibly small flash player with 128/256/512/1024 MB storage, has a mic and FM radio and and Vorbis. The YP-T6 has problems to play Vorbis files created with older encoder-versions.
The YP-T7 has either 512MB or 1GB capacity and supports the same audio formats, which also applies to the YP-F1. It can display JPEGs on its color display.
The YP-T9 supports Vorbis with firmware 1.50 and higher. The older firmware also supports MTP transfers only. Note that new firmware is available in two versions, MTP and UMS. Units purchased in US/Canada come with MTP firmware but can be reflashed with UMS firmware from Samsung's download site.
While the spec sheet for the YP-T9 lists Vorbis support, this is missing from the product package and from the user manual. Samsung tech support could not confirm that the player would play Vorbis files.
The YP-C1 has similar specs, including Vorbis support; at the time of writing, it seems to be readily available only in Korea and China.
The YP-53, a small flash player with 128/256/512/1024 MB storage, mic, USB 2.0 and FM radio, supports Vorbis(-q >= 0) with Firmware 1.200.
The YP-U1 is a small (2,38 x 8,78 x 1,35 cm, ~32g) flash player with 128/256/512/1024/2048 MB storage. The player has a LCD b/w display and an integrated accumulator that is charged via USB. It supports USB2.0 and has an integrated USB-plug that can be flipped in and out, so no cable or adapter is needed. It supports directory structures.
The YP-U2 sold in the US (YP-U2J) does not support Vorbis playback at all, despite what the website claims. Flashing an international firmware for the YP-U2XB allows Vorbis playback on US models (it also turns the player into a USB drive, so that WM10 isn't required to transfer files over. Note that certain international firmwares may remove the FM radio feature or hang the YP-U2J. See the appropriate link below for info on getting a hold of the correct Vorbis-compatible firmware.
- YP-U2J, YP-U2JQB, YP-U2JQB/XAA: observed US/Canadian models. PlaysForSure, no Vorbis
- YP-U2X, YP-U2Z, YP-U2XW, YP-U2ZB, YP-U2ZW: models supported on Samsung Hong Kong website as of 2007 August 19. These support Vorbis, UMS. B and W seem to stand for Black and White.
The YP-U3 sold in the US (YP-U3J) supports Vorbis playback with firmware versions 1.08 and 1.10 - quality levels 3 and 6 have been confirmed to work. Multi-track playback is not gapless - there's a pause of a few tenths of a second when switching between tracks. The US version is an MTP device (rather than a USB Mass Storage drive) and requires WM10, or libusb support (e.g. in Amarok) to transfer files. Vorbis tags are extracted and displayed correctly during track playback. Proper artist/album/track indexing requires that the program downloading the tracks to the YP-U3 extract the tags and include the information in the MTP download operation - the YP-U3 will not do this automatically.
"International" versions of the YP-U3, running versions of the firmware ending in an odd digit, function as UMS drives rather than MTP media devices. It is possible to reflash US (MTP) models with the UMS firmware, following the steps here and downloading the firmware and tools here.
The YP-Z5 is a player with color screen, 1/2/4 GB flash memory, USB 2.0 and Vorbis support (firmware versions 1.06US, 2.28US), albeit not officially mentioned on the manufacturers website.
